This demo is based on the GD32307C-EVAL-V1.1 board, it shows how to use the function
of oversample and shift. In this demo, 16 times ratio of oversample and 4 bits shift
are configured. PC3(channel13) is chosen as analog input pin. The ADC conversion begins
by software,the converted data is printed by COM0.

The analog input pin should configured to analog mode.
